FIELD OF THE INVENTION This invention relates to showers, conventional bathtubs, or walk-in bathtubs. In particular, this invention relates to folding doors for use with showers, conventional bathtubs, or walk-in bathtubs.
BACKGROUND OF THE INVENTION Shower doors are often used with showers, conventional bathtubs, or walk-in bathtubs to allow privacy and to prevent water splashing over the bathroom floor. In many cases, rigid panels are used which slide in place by means of top and bottom rails having guiding channels therein. Alternatively, hinged panels are opened and closed, with the top and bottom of the panels maintained within these same channels.
The disadvantages of using shower doors with tracks include:
-
- Access to the bathing area is limited.
- Installing the tracks of the shower doors is difficult.
- The track often appears unattractive.
- Cleaning the tracks is difficult and debris tends to accumulate.
- The accumulation of debris worsens the performance of the door.
- Bathing children and other dependent individuals can be a challenge due to the presence of the top and bottom tracks.
- Wheelchair access is limited by the bottom tracks in a shower.
It would be desirable to have a hinged door design that that can open either to the side, inside or outside of the walk-in tub. In addition, it would be advantageous for the hinged door design not to require a top rail which can interfere with entering or exiting the bathtub or shower, or with bathing by a carer. Further, it would be advantageous for the hinged door design not to require a bottom rail which would be prone to the accumulation of dirt, mold and the like, and also interferes with access.
SUMMARY OF THE INVENTION According to one embodiment of the invention there is provided fully trackless, frameless bi-fold doors for use with a conventional bathtub, shower, or walk-in bathtub. The doors open fully to allow access to a full shower or conventional bathtub by the user.

Referring to FIG. 11 there is shown a view of the walk-in bathtub 22 of FIG. 4 without the doors 2.
It will be seen that there is no track at the bottom or top of the doors 2. These are the first fully trackless shower doors 2. The two way trackless, frameless, bi-fold shower or conventional bathtub doors 2 open fully to allow access to a full shower or conventional bathtub 20 by the user.
The frameless bi-fold doors 2 allow for easy cleaning of both the doors 2 and the conventional bathtub 20 or shower. The doors 2 are coated with an easily cleaned coating allowing easier glass maintenance
Adjustable wall jams 4 (side rails) are provided for the wall assembly which allows the doors 2 to be adjusted, as required, to enable the placement of a magnetic seal strip 18 to close the doors 2.
Hinges are made of extra strong durable materials to allow the weight of the doors 2 to operate with ease.
(i) Conventional Bathtub When used with a conventional bathtub 20, as shown in FIGS. 1 to 8, the absence of a bottom track allows parents and carers to bathe babies and other dependent individuals in a conventional bathtub 20 without the discomfort of leaning over the track.
The bi-fold doors 2 can open inwards into a conventional bathtub 20 if needed and also open outwards out of the conventional bathtub 20, thus allowing a full 100% bathing access.
(ii) Shower When used with a shower, as shown in FIG. 9 the user or carer has the ability to drive a wheelchair into a shower because there is no bottom track. Similarly, as there is also no upper track, a carer is able to walk easily into the shower with a patient without hitting their head on the upper track.
Hinges 10 bi-fold in both directions allowing the doors 2 to open in both directions into a shower or out of a shower for full user optimization.
(iii) Walk-In Bathtub
When used with a walk-in bathtub 22, as shown in FIGS. 10 and 11, the trackless, frameless bi-fold doors 2 allows full access to persons helping an individual in a walk-in bathtub 22 with a door. The bi-fold doors 2 creates a full showering seal on the entire walk-in bathtub 22 including the movable door area.
The trackless, frameless bi-folding fully open doors 2 creates an entire seal throughout the entire walk-in bathtub 22 allowing the person using the walk-in bathtub 22 to enter into the walk-in bathtub 22 by the doors unobstructed by a door frame.
The bi-fold doors 2 fully open to allow persons using the door in a walk in bathtub 22 to have a person help them unobstructed when bathing or showering in a walk in bathtub 22 with a door.
The scope of the claims should not be limited by the preferred embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
